' (ci. 24S-354) K 1 Claim.

This @invention relates to a portable prop or support designed for use in supporting Celotex or similar ceiling or wall-board material, while the material is being nailed to ceiling beams.

An important object of the invention is to provide a support of this character which may be readily and easily extended or adjusted to different heights, to support the ceiling boards againstl the ceiling beams, in constructing ceilings of various heights. l

Another object of the invention is to provide a support including pivoted arms adapted to be swung outwardly providing a wide supporting Surface for contact with the ceiling board being positioned, to hold the ceiling board against buckling or moving, during the nailing or securing operation. v

Still another object of the invention is to provide a support which may be folded into a small and compact article to facilitate the storing and transportation of the prop.

With the foregoing and other objects in view, whichwill appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein described, may be made within the scope of what is claimed, without departing from the spirit-of the invention.

Referring to the drawings:

Figure 1 is an elevational View of a prop or support, constructed in accordance with the invention.

Figure 2 is a longitudinal sectional view through the support; when in its extended position.

Figure 3 is an elevational view of the support in its folded condition.

Figure 4 is a sectional View taken on line 4 4 of Figure 2.

Figure 5 is a sectional view taken on line 5--5 of Figure 1.

Figure 6 is a sectional view taken on line 6--6 of Figure 1.

long. These pivoted feet embodyspaced members between which brace bars 9 are pivotally mounted, the upper yends of the brace bars 9 adapted to extend to a point within the upper ends of the cutout portion of the lower section 5, where they engage the shoulders I0 formed at the inner end of the cutout portion, thereby bracing the pivoted feet to hold the pivoted feet 8 in their extended positions.

The reference character II indicatesV a foot member which is hingedly connected to the lower end of the lower y section 5, by means of the hinge I2. The foot II extends to a point-under the lower end of the lower section 5 where it has hinged connection with the foot I3 extending laterally at the opposite side of the -lower section 5. A hook indicated at I4 is pivotally connected with the lower section 5, and is adapted to hook into the eye I5l secured to the upper surface of the foot I3. Thus it will be seen that due to this construction, when the pivoted feet at the lower end of the lower section 5 are extended, they will be held rigidly against movement, to support the prop in an upright position. It will also be seen that by swinging the feet upwardly to a position as shown by Fig. 3 of the drawings, the feet will be moved into close engagement with the lower section 5 to facilitate storing or transporting the prop. v

The upper section 5 is hollow, and is adapted to recieve the lower section 5, as shown by Fig. 2' The reference character I6 in-4 of the drawings. dicates a drum which is extended through the upper section 6, near the lower end thereof, the drum I6 being provided with a crank I'I at one end thereof, whereby the drummay be rotated. A cable indicated at I8 has one of its ends wound on the drum I6, the opposite end thereof being connected to the lower section 5, at the upper end of the lower section as shown by Fig. 2. Thus it will be seen that as the crank I1 is rotated to wind the cable I8 on the drum I6, the upper section 6 will be elevated for supporting a ceiling board to be nailed to ceiling beams in building construction.

Notches I9 are formed in one edge of the lower section 5, 'and are adapted to be engaged by the pivoted plate 2li which is secured at the lower end of the upper section 5. When `the upper section 6 has been moved to its proper supporting posiftion, the plate 25 is moved to engage the notch I9, falling opposite to the inner end thereof, thereby providing a support for the upper section and article or ceiling board supported at the upper end thereof.

As clearly shown by Fig. 5 of the drawings, the upper section 6 is rectangular in cross section and at each side face of the upper section at a point adjacent to the upper end of the upper section, is an arm 2|, the arms being so arranged that they extend at right angles with respect tol each other and the upper surfaces of .fthe arms present a. supporting surface to be positioned against theeceilingbboard which is to be attached to the ceiling beams ofthe building.` When the prop or support is in its folded lcondition, .these arms 2| extend upwardly in substantially parallel relation with respect to each other. When the arms are moved to their active or `supporting positions, they are moved to the Yposition shown by Fig. 1 of the drawings, the lower -e'dges of the arms 2| resting on :thelupper ends of the stops 22, so that the arms Vwill be rmly held in their horizontal supporting positions.

From the foregoing it willbe seen .that due to th'e 'construction 'shown and described, I have provided a support or prop which may be used in supporting ceiling boards in their proper positions while they are being nailed to the ceiling beams of a building, to the end that the ceiling board will be held against; buckling or bending, during the nailing operation.

What is claimed is:

A ceiling prop comprising telescoping upper and lower sections, the lower section being formed with openings near lthe lower end thereof, presenting a shoulder, pivoted feet secured to the lower section, bars pivotally connected with the `feet and adapted to move within the opening of the lower section, the upper ends of said bars adapted to engage the shoulder, holding the device in 'an upright position, and pivoted arms Aat the upper end of the upper section, said arms being adapted to swing to horizontal positions for supporting an article thereon.
